New England Distribution

Non-native: introduced
(intentionally or
unintentionally); has become naturalized.

County documented: documented
to exist in the county by
evidence (herbarium specimen, photograph). Also covers
those considered historical (not seen in 20 years).

State documented: never been
documented from the
county, but known from the state. May be present. Or,
may be restricted to a small area or a habitat (alpine,
marsh, etc.), so unlikely found in some
counties.

Note: when native and non-native
populations both exist in a county, only native status
is shown on the map.
